12611 divided by 30 
Our goal is to divide 12611 by 30.

Going ahead to step 1:
30 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 30

Moving on to step 2:
30 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 30

On to step 3:
When dividing 126 by 30, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 120 from 126 leaves us with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 30

Moving on to step 4:
30 goes into 61 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 42.0
Subtract 60 from 61 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 30

Let's proceed to step 5:
30 can be fit into 11 0 times, resulting in a remainder of 11.
The next digit of our result is 0. 
Result so far: 420.0
If we subtract 0 from 11, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 6:
30 can be fit into 110 3 times, resulting in a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 420.3
Deduct 90 from 110 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 420.36
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 30 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 420.366
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 420.366 with a remainder of 0.002.
